Model-actress Ruby Rose has accused Katy Perry of sexually assaulting her two decades ago.

The "Orange is the New Black" star alleged in a series of posts on Threads Sunday, April 12, that the pop star assaulted her at an Australian nightclub when she was in her 20s.

Rose first commented on a Complex Music Threads post mentioning Perry, saying, "Katy Perry sexual [sic] assaulted me at spice market nightclub in Melbourne. Who gives a [damn] what she thinks."

In further posts, she thanked fans for their support after sharing her allegation after "almost 2 decades."

"I was only in my early 20s. I'm now 40. It has taken almost 2 decades to say this publicly," she wrote. "Though I am so grateful to have made it long enough to find my voice, it just shows how much of an impact trauma and sexual assault takes. Thank you for seeing me."
